Standard Practice for Manual Sampling of Stationary Coal from Railroad Cars, Barges, Trucks, or Stockpiles

Importancia y uso:

5.1 These guidelines provide procedures for manually collecting gross samples from beneath the exposed surface of coal in railroad cars, barges, trucks, or stockpiles taking into account the wide variety of conditions that may be encountered. The samples are further processed for the laboratory to provide estimations of the coal quality. The use of this practice is conditional upon agreement among all interested parties concerning all relevant details of sample collection before sampling begins. These details include, but are not limited to: lot size; number and mass of increments; the size, shape, and manipulation of the increment collection devices; location of increment collection site or sites; circumstances under which increments are not to be collected or suspended; and safety precautions. It is preferable that such agreements be in writing. The user is cautioned that samples so obtained do not represent material below the point of penetration.
